Overview

This HDBaseT extender Kit, extends HDMI up to 330 feet (100 Meters) over a single CAT5e or CAT6 cable. The extender supports Ultra HD and Full HD resolutions (4K / 1080p) with support for 3D and the accompanying 7.1 digital audio. For added versatility, both the transmitter and receiver can be powered by the same single power source using Power Over Cable (POC). The versatility of this video extender makes it an ideal solution for digital signage applications in large buildings such as commercial shopping centers, stadiums, schools, and hospitals.

What is HDBaseT?

HDBaseT is a standardized, zero latency, video distribution technology that’s revolutionizing HDMI distribution. HDBaseT uses an advanced method of modulation that enables you to distribute uncompressed HDMI audio and video, along with additional signals such as 100BaseT Ethernet, IR, RS-232 serial and power over cable.

Extend More than Video with HDBaseT

For greater versatility than a traditional HDMI extender or HDMI cabling alone, this HDBaseT extender offers HDMI + Power Over Cable in a single kit. The added benefit of power over cable means you’ll only need one power source at either side of your extension, great for extending to areas where power outlets may be limited.

Astonishing 4K picture quality from an impressive distance

With the A/V industry quickly adopting 4K as the new high-resolution video standard, long range video distribution can be a challenge with standard HDMI cables beginning signal degradation at 30 feet. With support for 4K you’ll be amazed at how HDBaseT maintains your Ultra HD picture quality, four times the resolution of high-definition 1080p, even at 130 feet away from your video source. Plus, because the extender supports High-Definition 1080p and lower resolutions at 330 feet away, you can comfortably use this extender to make any video source look great.

Hassle-free, Professional Installation with a Single Cable

This extender has been specially crafted for a smooth, tidy setup. HDBaseT technology allows for single cable installation, for seamless integration using existing CAT5e or CAT6 infrastructure, avoiding the hassle of running multiple cables, while reducing potential failure points. Plus, the added benefit of power over cable means you’ll only need one power source to power both your extender and receiver, great for extending to areas where power outlets may be limited. Mounting hardware is also included for both the extender and receiver for discrete, professional mounting.

The ST121HDBTPW is TAA compliant and backed by a 2-year StarTech.com warranty with free lifetime technical support.

Frequently Asked Questions

Before You Buy

You should only use video converters and extenders if it is absolutely necessary to do so. In many cases, most video converters and extenders are not necessary if you purchase the correct cable.

The following table lists the maximum length of cable for common video standards.

Video standard

Maximum length

DisplayPort

50 ft. (15.2m)

HDMI

50 ft. (15.2m)

DVI

50 ft. (15.2m)

VGA

200 ft. (71m)

Note: StarTech.com offers cables longer than what is listed above, including active cables, which typically include built-in active signal boosters that allow for longer cables. Active cables are specifically designed to exceed the suggested maximum lengths and are tested at the listed specifications (for example, the maximum listed resolution).

Video adapters

Video adapters passively adapt a cable from one connector type to another. Video adapters do not change the signal type, or change the video standard.

Examples of common applications for adapters include the following:

DVI-I to VGA

RCA to BNC

Mini DisplayPort to DisplayPort

Couplers (female to female, or male to male)

Note: You can use a coupler to extend a cable for a short distance. However, each coupler that you use can introduce signal loss, which degrades the signal quality.

Video converters

Video converters actively process and change the signal type from one video standard and convert it to another standard. They are typically used to convert digital to analog and vice versa, but can be used to convert a digital signal to another digital video standard (for example, HDMI to DisplayPort).

Video converters work over short distances from the source to the destination: up to 15 feet or 3 meters.

Video extenders

Video extenders convert an input signal to a higher voltage for transmission over longer distances and then convert the input signal back to the original video standard. The input and the output signal will match on a video extender, as the same video standard is maintained end-to-end. If a cable is extended with adapters or converters, the signal quality degrades.

Was this information helpful?Yes No

If you need to use a video extender with a video adapter or converter, you should position the adapter or converter as close to the video source as possible. For example, if you need to take a VGA signal from a computer and send it 200 feet to an HDMI® projector, you should convert the signal from VGA to HDMI and use an HDMI extender.

The set-top box must support devices being connected between the video source and display. If the set-top box requires a direct cable connection between the video source and display, it won't work with this video extender.

Was this information helpful?Yes No

This device outputs HDMI video signals. If you have a display or video destination that uses another type of video connection, there are ways that you can convert the video signal or connection. These options are outlined below and organized by the target connection.

HDCP

When you consider whether to convert an HDMI video signal to another connection type, it is important to know if the media that is being converted from the HDMI video connection is protected by High-bandwidth Digital Content Protection (HDCP). If the media is protected by HDCP, you cannot convert to analog video connections because they do not support HDCP. You may experience this issue when you use devices like Blu-ray players, DVD players, and certain gaming consoles.

Was this information helpful?Yes No

This device has an HDMI input port. If you have a video source that uses another video connection, there are options available to convert the video signal or connection. These options will be outlined below for each video source connection.

Was this information helpful?Yes No

To get the highest quality signal from your source to your display when you use an HDMI extender, do the following:

Make sure that the HDMI versions of the source, extender, and destination are compatible. For example, if you require 3D support, make sure that all of the devices can support 3D over HDMI.

Use the least amount of adapters, splitters, or converters as possible. Each device that you use in your setup creates additional points of potential failure and creates more steps for an HDCP key to hop through, which may cause issues with older displays. For more information on HDCP, refer to the following FAQ: http://www.startech.com/faq/video_signal_converters_HDCP.

Use an HDMI extender that exceeds the requirements of the setup. For example, if you need to extend the signal 200 feet, it is best to use an extender capable of more than 200 feet.

Make sure that all of the CAT 5/6 runs are as straight as possible, with the least amount of coiling.

Make sure that all of the patches, wall jacks, and cables use the highest possible CAT specification, (for example, CAT 6), and were tested to conform to the standard.

Troubleshooting

When you troubleshoot issues with a video extender, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

Video and Ethernet cables

Video extender

Video source (such as a DVD player or computer)

Video destination (such as a monitor or projector)

Note: When you are testing setup components, you should avoid using video adapters. For example, if you are converting a VGA source to HDMI for use with an HDMI extender, you should use an HDMI source when you test the components.

To test your setup components, try the following:

Use the cable, video extender, video source, and video destination in another setup to see if the problem is with the components or the setup.

Use a different cable, video extender, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

Test each cable individually.

Use short cables when you are testing.

When you test the video source and video destination, it is recommended that you do the following:

Remove the video extender from your setup and test to make sure that the video source and video destination work together without the video extender.

Test to make sure that the video source and video destination work together at the resolution that you want to use.

Note: In order for your setup to work properly, the video source, extender, and destination all need to support the resolution that you are using.

This device supports up to 4Kx2K resolutions @30 Hz with a color depth of 8 bits. If you are running a 4K resolution at a refresh rate higher than 30 Hz or a color depth higher than 8 bits, your display will appear blank.

To resolve this issue, you need to lower the resolution, refresh rate, or color depth, by completing any of the following:

Connect a display to OUT 1 that is only capable of 4K at 30 Hz with a color depth no higher than 8 bits.

Connect the least capable display to OUT 1.

Connect an additional display to your video source (for example, a video card in a computer) and use this display to reconfigure the display connected to OUT 1 to run at 30 Hz and 8 bits color depth (or lower).
